Testing

This chapter is an overview of the testing procedures for the

VAXstation 3100 model 38 and 48 systems. Since the testing procedures

for the VAXstation 3100 models 38 and 48 are similar to the testing

procedures for the VAXstation 3100 models, this chapter will not

repeat the information described in Chapter 1 of the VAXstation 3100

Maintenance Guide. If you are not familiar with the diagnostics available

on the VAXstation 3100 models 38 and 48 systems, you should read

through the testing procedures in Chapter 1 of the VAXstation 3100

Maintenance Guide.

The label on the back of the system box indicates which model you are

working on. The WS42A-xx model number on the label identiﬁes the

VAXstation 3100 model 38 system and the WS42B-xx model number

identiﬁes the VAXstation 3100 model 48 system.

All testing is done while in the console mode and diagnostic tests are

ROM-based.

This chapter contains an overview of the following procedures:

• Running power-up tests

• Running self-tests

• Running system exerciser diagnostics
